MICROMETRIC SPACER FOR TYIE-WRITING MACHINES.

Application filed November 19, 1912,'Serial No. 732,

. To all whom. it may concern:

- Be it known that I, BnaNAnno Onnoiinz, a citizen of Argentina, residing at Cordoba, in the Province of Cordoba, Argen- Micrometric Spacer for chines, ofgwhich the following is a "full, clear, and exact. description. I

The object ofthe invention isto provide a new and improved micrometric spacer for typewriting machines, arranged to enable the operator to quickly and accurately set the platen-turning mechanism for producing any desired distance between succeeding lines of the written matter, also enabling the operator to accurately follow ruledpa- 'per' without being obliged to turn the platen by hand.

In .order to accomplish-the desired result use is made of a wheel rotating with the cylindrical platenv of the typewriting ma-' chine, a manually-controlled gripping device adapted: to engage the rim of the said 'wheel to turn the latter, and an adjustable regulating device for increasingor decreasing the throW'.,.of the said gripping device according to the distance between successive lines. p A practicalembodiinent of the invention isrepresented in the accompanying drmw ings forming a part of this specification, in which similar characters of referenceindicate corresponding parts in all the views.

Figure 1 is a plan view of the micrometric spacer as applied to an Underwood typewriting machine; Fig. 2 is an enlarged elevation of the left-hand end of the same, parts being'iI -section; Fig. 3 is a cross section of the same; Fig. 4 is a plan view of the same, parts being broken out; Fig. 5 is a sectional front elevation of the same on the line 5-5 of Fig. 2; section of the same onthe line (3 6 of Fig. 4; Fig. 7 is a'sectional side elevation of the brake mechanism for the. cylindrical platen; Fig. 8 is an enlarged-plan view'of the microlllElillC adjustment; Fig. 9 is a perspective view of the cam operating'lever; and Fig.-

G of the platen frame C adapted to be raised and lowered on the carriage for upper and lower case type by the usual rock arms D engaging studs E arranged on the platen frame G.

()n the platen shaft A is secured or formed a wheel F having a rim F adapted to. be engaged at ,the inner surface by a gripping shoe or block i: formed on or secured to a gripping arm G fulcrumed at G on a covering plate H for the inner faceof the wheel F. The covering plate H- is provided with a pin H (see Figs. a and (3) engaged by one end of a spring I coiled around and attached to the bearing C the platen frame (1. The covering plate H is loose on the platen shaft A and is under tension exerted by the spring I.

The gripping arm engaged by a cam arm J fulcrui'ned at 'J' on the covering plate H and the free end of the cam arm J is adapted to be engaged by a shoulder K" (see Fig. 3) forn'ied on the fulcrum end of a lever K loosely fulcrumed on the platen shaft A. The inner portion of the lever K as well as the arms Gr and J are arranged within the opening of the wheel F and the upper end K of the lever K is bent to one side and extends through a cut-out portion in the covering 'as plainly indicated in Fig. (3. The outer free ally connected by a link L with a. slide N extending transversely and mounted to slide in suitable bearings arranged on the platen frame (.3. The forward end of the slide N is provided with an angular lug N engaged by an arm mounted to turn on a stud 0 carried by the carriage, and on the arm 0 is secured a handle 0 adapted to be taken G is adapted to be end of the lever K is pivot hold of by the operator to impart a swinging a motion to the arm 0 with a view. to giving a transverse sliding inovement'to the slide movement is given to the gripping arm G which .by its gripping blOClC G new engages-the inner surface of the flange F to rotate the wheel F. As the wheel F is secured on the platen shaft A it is evident that the platen shaft A is turned and with it the cylindrical platen B. The gripping block G is normally out of engagement ping block Gin gripping contact with the rim F. Thus, on starting the'handle O in the direction of the arrow a (see Figs. 1 1 and 4;) the gripping block G is engaged-- with the'rim F and during'the remainder ofthe moyefnent given to the handle in the direction of the arrow 0; the wheel F is turned 1n the"direction of the arrow 72 and with it'the cylindrical platen BI It is understood that the pressure exerted by the shoulder K of the working lever K on the free 'end of the camar'm J not only causes thesaid arm 'J to swing slightly outward for gripping purposes, but also carries the said arm J. along, thus turning the covermgplate in the direction of the arrow 1) against the tension of its springI.

When the handle 0 is. released the block- G releases its grip on the rim F of the wheel and the spring I =pressing'the covering plate H'returns the latter tonormal po sition and with it the arms G and J pivoted user can accurately set the device to any deon the saidcovering plate H. j It will also be noticed that the return movement of the cam lever J causes a return rocking of the lever K whereby the link I imparts a return sliding movement to the slide N and thus returns the arm 0 and the handle 0 to normal position.- By reference to Fig. .3', it will be noticed that'the cam arm J engages the gripping arm G at the free end thereof, and the free end of the cam arm J is engaged by the lug K of the oscillating lever K so that an exceedingly powerful action is hadto swing the gripping -arm G outward at the time the handle 0 isstarted, to insure a firm, positive gripping of the block G with the rim F of the wheel F. The forward rocking movement given to the covering plate Hand the arms Grand J carried thereby is limited and "for this purpose the at the-lefthand side-of the machine.

plate H is 'provided with a stop lug H adaptedto movein contact with the stud E The return movement of the covering plate H is limited by the lug H abutting against the lowerend of a vertical screw rod P screwing in thetop of the platen frame C and pro vided ,at its upper end with a head P adapted to be taken hold of by the operator for turning the screw rod 1 so as to screw the same up or down to increase or decrease the throw of the covering plate H and the arms Gand J carried thereby. 7

' In order to indicate the amount of the throw given t the wheel F, use is made of .an indicator arrangedas' folloWspOn the covering plate H is secured a pointer H extending over the peripheral face or the wheel F (see Fig. 8) and ind cating on a segment If fixedon the left-hand side of the platen frame C, the segmentbeing-provided the said brake lever- Q,"-'-is pressed on .attached to the screw rod head P, and. de-

pends from the same to indicate on a; gradu- 1 5'.

ated link P attached to the top of the platen frame C. The circular graduation on the disk P represents linear measurement, and the total length indicatedcorresponds to the 'distance between adjacent marks of the g0 graduation on the segment H so that on one complete turn of the screw rod' P the I pointer P? makes a complete turn on thedisk P while the. pointer H moves from onev mark of the graduation on the segment H 5 to the next following one. H By the arrangement described, the user of the machine 'can' see at a glancethe amount of the throw to which the devicehas been set, and when turning the screw rod P the 9 sired throw on watching the movement-of the pointers H and P.

to space succeeding lin'esthe desired distance 10 *apart. After the screwrod P has been ad-" justed it is locked in place by a lock nut P screwing on the screw rod P-against the 7 upper face of the disk P It will be noticed that when the parts are in normal dormant position the platen vB can be turned by hand as the spacing mechanism is then practically completely free of the platen. It will further be noticed that by the arrangement described the most -mi- 11o nute'. adjustment can be had relative to the distance between successive lines by adjust-- ing, the screw 1 correspondingly. y In order to prevent the platen. B from:

being shifted toofar owing to the inomenturn given to the platen while turning it, use is madeof a brake shoe Q engaging the peripheral face of the rim F of the wheel F.

The brake shoe Q is held on a brake lever Q,

fulcrumed at Q on the platen frame -C,l-)and,

y a spring Q to hold the brake shoe Q in frictional contact with the peripheral face of the rim F. On the rear end of the brake lever Q is journaled a shaft Q carrying a cam wheel-Q, in contact at its peripheral face with the inclined plate forming part ofthe platen frai'ue C (see Figs. 2, 3 and 7). On the shaft Q is also secured a handle Q under the control of the operator for turning 13o claim as new and race Patent:
